Directed Line Segment

What is the terminal point of vector $$\overrightarrow{AB}$$  ?

What is the initial point of the vector $$\overrightarrow{AB}$$  ?

Vector  $$u$$  and vector  $$v$$  are equal vectors.

In the diagram, OBR and AQR are straight lines such that OB=BR and QR=2AQ. Given that \overrightarrow{OA\ }=a and \overrightarrow{OB}=b, express \overrightarrow{AR} as simply as possible in terms of a and b.
